Robo interesting post. I use oil field "Nut Plug" lost circulation material. This is made from a very fine grade of ground pecan hulls. Most companies will give you broken bags of plug. I also experiment with cleaning this free media. Dedicated re-loaders pushing the line over the years are the brains behind reloading.

I could certainly afford to buy new media. It started as an experiment to see if it could be done. Now it is an experiment to see how long it can be done. I have media that is 15 years old or better and has cleaned literally a quarter million cases.

Reloaders are some of the original recyclers. I am being environmentally conscious.

Same here, my media is only 10 years old and has cleaned many thousands of cases. An old reloader told me to put some in rice, dryer sheets and a couple of cap fulls of paint thinner every couple of cleanings. I have done that all this time and all my brass comes out nice and shiny after 1 1/2 hours or less.
